TO ALL WHOM IT MAY'GONCERN:

Be it known that I, WILLIAM A. ROBINSON,0f the city of Grand Rapids, inthe county of Kent, and State of Michigan, have invented a new andimproved Mop-Head and I hereby declare that the following is a full andexact'description of-said invention, reference being bad .to theattached drawings, making a part of this I specification.

Said invention, when constructed of iron, consists of a socket, a, toreceive the handle, a transverse head," b, two wire bows, 'c a, two arms01 d, and two links e e. ,There is a thickly-set row of pointed teeth,f,in the centre of the head 1), extending the whole length of the head."-There is a tenon-like projection,- g, on each end of the head, whichprevents the bows c a from passing back and i'orth over the head. Thearms d d are attached'to the opposite end of the socket from the head,and extend on a. line parallel with the head, and are supported bybraces h k, resting on the head. Inj the outer end of the arms d d theremay be a mortise, it, as shown in the drawings, or slots,--to receivethe endof the bows 'c c. The links e e slide on the bows c c, from themortise or slots to the end of the head, and when brought back, theblows a 0 may be opened to receive the mopcloth, which being passed overthe head and through the bows, will ,be brought on to the teethfiandfastened there by sliding the links e e down towards the end ol' thehead. The teethfserveto prevent the cloth from coming out, and also fromcoming together during the process of wringing. I I

The said invention may also be constructed of ,wood and wire, withoutthe cast head, in which case the head will be madeofditb'od. The teethmay be made of wire, andginserted in the centre of the head like spurs,

a short distance from'each other, or their equivalents. A brace, made ofwire, may be inser.ted in each end of the head, and extended anydesirable distance upward, when it will be coiled once and a halfround,forming an opening corresponding with the mortise z' 2'. abovedescribed, toreceive 'und hold the ends of the bows c c,

and from thence it will be turned toward, extended to, and inserted inthe handle. The liukse e are used on the bows of this style ofL'nop-he'adin the same manner and for the same purpose as on the ironhead above described. v 5

What I claimas my invention, and desire to'secure by Letters Patent,is-- 1. The combination of the arms 01 d, the socket ayand teethf,andthe mode thus provided'for attaching and holding the bowec a,substantially as and for the purpose. described. I

2. The arrangement and combination of the socket a, head b, bows c c,braces 7th, with the arms (2 d, links e e, and teethf, substantially asand for the purpose intended. I
